BTA on the move

As stated in the title, my RBTA is on the move again in my tank. He was up in the corner of my tank for 3 weeks and this morning I discovered that he has since moved down into the tank and mounted on a rock. Do they continuously move in the tank? Should I be concerned?
All my params are good, I do 10% weekly WC's and there has been no changes in my lighting length or output.
I'm new to anemone care and probably a little paranoid...

 

For some odd reason I never had mine move around much. A couple inches here and there but no big walks. Judging by others post though it seems they do indeed move around a lot.

 

I had a GBTA that covered the whole tank at night (biocube 14), now i have an RBTA that wont leave its 2" by 2" rock. lol

 

I've had one move all over my tank, then i spot fed it some shrimp and it stayed put. How new is it to your tank? I took a table shrimp that had been frozen, thawed it out, cut it into a manageable size piece, and fed it. Just wait until its in a spot you like and try it, may work.
